This inventionrelates. tov a: wheel mounting.

More speciiically` it relates to va spring construe'` tion for connecting'ta.: supporting wheel to` a; vehicle; substitution of ordinary Wheels with steel rims for wheels Withrubber tires.. Since awheel having steel rims hasno flexibility'. someresiliency must be provided in the connection between the wheel and the vehicle which it supports..

An object ofthepresent-invention is to. provide an improved. wheel mounting;

Another object is;..the provision of a resilient' wheel mounting- A Still another obj ect Vis to provide awheelmount-Y ing for a vehiclelinvolvingf springs:

observed from Figure-6 thatthe plate 4lll'is of narrow, rectangular shape, and the plate 4I is of generally triangular yshapeand extends completely ..across= theeridtotftheoaxle 36. A stub-:axle7 551,42 extendsv through. and is secured. tothe plates.-

4U and 4I by welding. A wheel 43 is mounted upon the stub axle 42. Secured to one end of the plate or arm 4| is a part 43a at one side of the axle 36. A bolt 44 extends through the part 43 and the bent portion 31 of .the strap 35. The bolt 44 has an enlarged head 45, upon which rests a v spring 46 embracing the bolt 44 and contacting the under side of the part 43a. A spring 41 embraces the bolt 44 and is positioned between the part 43a and lthe bent portion 31 of the strap 35. A nut 48 retains the ybolt 44 in position. The journaling of the stub shaft 39 in the tubular member 38 in the fitting 35 allows the plates 40 and 4| and the wheel 43 to pivot about the axle 36 on an axis determined by the stub shaft 39. The springs 45 and 41, which are opposed to one another, limit this movement and provide a cushioning between the wheels 43 and the axle 3B.

It will be apparent from the foregoing description that new and novel mountings for wheels upon an axle have been provided. In the two modifications described, there are provided littings secured to axles. Wheels are resiliently connected to the axles by means of pivot arms and bolts embraced by opposed springs, which provide a cushioning limit to the movement between the wheels and the axles.
